Will Brady Hoke and Doug Nussmeier be able to hang onto prized 2015 running back Damien Harris? Carlos Osorio

One of the biggest recruiting story lines surrounding Michigan football over the past month has been a major question mark.

When it comes to five-star 2015 running back Damien Harris, is he staying or going?

Speculation has run rampant about the possibility of Harris, ESPN.com's top-ranked running back in 2015, opening up his recruitment in the wake of Michigan's 7-6 season and the ultimate firing of offensive coordinator Al Borges.

Borges seemed to be one of the main threads tying Harris to Michigan in the recruitment process, as Harris' prep coach at Madison Southern (Ky.) High School -- Jon Clark -- was a staffer at Auburn with Borges in 2007.

Once the Wolverines fired Borges earlier this month, Harris once again made a few Twitter waves by expressing his surprise.
